This invention pertains new and novel means for marking the streets andsafety zones in certain localities where vehicle traffic is exceedinglyheavy and dangerous.

I 5 The present custom ofpainting traffic lines to indicate centerstreets, cross walks on streets and street car Zones, etc., has the d1sadvantage that the lines wear off and must be repainted constantly.

It has also been found that white, black, red and amber colors are themost suitable colors for mankers to insure visibility, and it has beenfound that markers that have a surface even of a light alloy metal asbrass,

copper or German silver do not bring the de= sirable results. v

The object of my invention isto provide a street traflic marker thatwill be cheap to ,manufacture and will provide at the same time thedesirable coloring to insure visibility,

and thus eliminate the painting of traflic lines. T

Another object of my invention is to so construct my traflic marker thatit will indicate '25 any desired coloring on the upper face of themarker, and that such color will be further permanently maintained byproviding studs or projections on said upper face of the marker in sucha manner that they will pro tect the recessed colored surfaces betweenthe studs or projections from wearing off while traflic moves on'theupper surface of the marker, since the studs'or projections will wardoff any object that may travel on the marker from getting in contactwith the recessed colored surface so as to efface the coloring. IAnother object of my invention is to add additional durability andattractiveness to the upper surface of the marker by covering or coatingthe said vupper face with baked enamel of any desired color, and to soarrange the studs or projections on its upper surface that it willprotect the chipping off of the enamel between the recesses .whentraffic moves over the upper surface of the marker.

Another object of my invention is to so construct my marker that when itis desired to economize in-the use of material of which the marker iscomposed that thebottom surface of the marker may be hollow and toprovide integral reinforcements inside of the hollow surface.

Another object of the invention is to so construct my improved markerthat it may be readily installed within the street pavement zoiniweMARKER FOR STREET TRAFFIC.

regardless of the material of which the street 'is constructed; that itwill be always maintained permanently in the desired position; and'thatit. may be disposedfiush with the surface of the street or slightlyabove the street surface.

'lhe foregoing and such other objects as may appear from the ensuingdescriptionare attained by the construction, arrangement and location ofthe parts hereinafter more fully described, illustrated in the accompanying drawings and more'p-articularly pointed out in the claim appendedhereto, it being understood that slight changes in the precise form,proportions, and minor details of construction may be resorted towithout depart- I ing from the spirit 'or sacrificing any of theadvantages of the invention;

In the accompanying drawings forming a part of this specification itwill be seen that: Figure 1 is a plan view of the improved .meansembodying my invention.

Figure 2 is, a transverse section thereof taken in theplane of thedotted lines 2-2 Fig. 1.

' Figure 3-i's a longitudinal section taken in d I the plane of thedotted lines 33, Fig. 1.

Figure 4 is a plan view of a slightly modified form.

Figure 5 is a section taken in the the-dotted lines 55, Fig. t.

Figure 6 is-a plan view of'further modified form. Figure 7 is across-section taken in the plane of plane of the dotted lines 7+7, Fig.6, and

Figure 8 is a plan View of one other slightly modified form. I

In the embodiment'of my invention as il- 'I lustrated it will be seenthat the numeral 1 designates a zone marker, providedat its lowermostportion with a laterally extending. flange 2, and formed with a centraldownwardly extended strengthening portion 3, a downwardly extended wall4 formed at the sides and ends thereof, while the inner por-- tion.thereof is hollow, the extended flange 2 serving to lock the markerwithin the street pavement, and in connection with the wall 4 tomaintain said marker in its fixed and permanent condition atall timesand under all conditions.

The upper or top portion of the marker is formed of a portion 5, curvedorarch-shaped from one side to-the other, its upper face or surfacebeing" formed with a series ofoutw'ardly extended projections 6, and aseries of recesses or depressions 7 intervening be-. tween sald proections', each of the saidrea cesses or depressions being preferablycurved or rounded at their ends and sides for the purpose of drawing'offforeign material that may collect between-the recesses and thus'maintainithe colored surface cleansed and visible as hereinafterdescribed. 1

, My improved marker is preferably coated or enameled over its upperface or surface with a suitable,'easily visible coloring material,preferably baked enamel, and while the projecting surfaces will form atop surface of metal, rubber, or other composition over which vtraflicmay travel, the recessed portions being out of contact'with the heavytraffic will always maintain its readily 'visible color, under allconditions, and owing to the ticular type of marker may be formed ofany.

sloping sides and ends of the depressionsor recesses, any dirt, dust, orother foreign material which may accumulate therein, is

.readily and easily cleaned out by the usual winds and rainfalls, thusalways maintaining a readily visible color to indicate the safety zonesand crossing lines to drivers of vehicles of all kinds, as well as topedestrians.

It will be readily perceived that this parsuitable or desirable materialpossessing the required strength such as castings, pressed sheet metalor a composition to be embedded or installed within. the material whichconstitutes the street pavement; that it may be coated or enameled withany suitable, readily visible coloring material, and that the marker maybe formed of any suitable or desirable dimensions, contour, or letters,which may prove most desirable for t e location and the purpose forwhichit is in ended to be used, that is, for street crossings, safetyzones;

I and side-walks.

By reference to 4 and5 of the drawings it- 'willtbe seen that a slightlymodified form of structure or marker is shown, said structureor'marker'to be installed within the street pavement, and is prov dedwith anoutwardly extended flange 8 at its lower end, while its top wall9 is provided upon 1t s upper face with a series of pro ect1ons 10 and10', said projections being of different pense with the expense offrequently painting the traffic lines and safety'zones on the streetpavements, which lines and zones are frequently invisible to thetraflic.

Referring to Figs. 6,7 and 8 of the drawings which disclose furtherslightly modified forms of the invention, the numeral 13 inllwhich isformed of any desirable material, said cover being provided with aseries of slightly raised or projecting portions 15, and depressions 16,formed intermediate said projecting portions, said cover being securedin any suitable or desirable manner to said-frame, said depression beingcoated or enameled with 1 any suitable visible color,

distinguishable coloring, and since the depressions are not subjected towear by the heavy traflic, the marker will always be easily and readilyvisible.

It will be understood that the projecting surfaces'may be suitablyserrated or roughened to prevent accidental slippingduring passagethereover. Having thus described my invention-what dicates a frame,having a removable cover preferably white baked enamel or any other I Iclaim and desire to secure by Letters Pat.- I

cut is: v

In a device of the'character described, a

structure having its top surface curved along the longitudinal andtransverse axes and provided over its entire surface with projections,the surface between same being coated with material to give samedistinct visibility, the projections being of such height and so spacedas to prevent tires from scraping the coated surface and to act as anon-slipping surface, the curvature of the recessedsurface being such asto, permit free drainage and to prevent normally, the collection ofdirt.
